摘　　要：本文在相关有效场理论框架内，应用类伊辛模型分析方法，研究了海森堡薄膜的临界行为.This paper attempts to present our study of the critical behavior of the Heisenberg film in the twoatom cluster model with two Heisenberg spins in the Ising surrounding. By use of the effective-field theory with correction, the dependence of the critical temperature of the Heisenberg film on the thickness, surfacte coupling of the film are investigated. The surface magnetism of the film is also discussed.
